My most skilled languages are Go, Python, and JavaScript/Node.js.
I use Go for backend API development, Python for general programming tasks such as Data Analysis,
Web Crawler, Machine Learning, Mathematics, and JavaScript/Node.js for
web programming by using frameworks such as Vue.js, React.js, Vuetify.js, and etc.

I frequently use Latex to type Math and CS homeworks. You may find some samples of my work here:
